The Liqui Moly 157 Motor Flush is a 300mL highly effective cleaning fluid designed to thoroughly clear the engine interior of troublesome deposits. This specialized formula brings all types of oil-soluble and oil-insoluble residues into suspension, ensuring their complete removal during the subsequent oil change. Utilizing Liqui Moly Motor Flush helps an engine, once cleaned and refilled with fresh oil, to develop its full performance characteristics, reduce wear, and extend its service life. It is applied to warm engine oil before an oil change, with the engine running at idle for approximately 10 minutes, followed by immediate draining of the old oil and replacement with fresh oil and a new oil filter. Confirmed technical details include a density of 0.825 g/cm³ at 20 °C and a pour point of -45 °C.
